listen(integer chan, string name, key id, string mes)
{
if(id == llGetOwnerKey(id)) //won't listen to objects unless they aren't in the region.
llSay(0,"whatever";);
}


What does the part ";(id == llGetOwnerKey(id)) " do in the above listen command? As you can see the // comment is a bit confusing as it is double negative. Does it mean that this id check is to make sure your object listens to objects that ARE in the region? Is it even necessary to use this or can I just ignore it?

The page it came from is here:

The double negative is literally correct. If an avatar's key is passed to it, the same key will be returned, since agents "own themselves." If an object's key is passed, it's owner's key will be returned, unless that object is outside the sim, in which case the key passed to it is returned. Ergo, won't listen to objects unless they aren't in the region. Or, less confusingly, will only listen to objects outside the region.

In OR out of the region. If an agent's key is passed to llGetOwnerKey, and they're in the region, it returns the agent's owner's key... which happens to be the key passed to it. If they're out of the region, it just returns the key passed to it. Same difference either way.

Edit: Perhaps the most succinct description of this filter is "Won't listen to objects in the same region."

I think Im gonna use that on a negative channel... that should filter users, so it should ignore anything on sim, and listen to objects off sim... im't thinking up odd uses for this now
